The total power in a three-phase balanced circuit, i.e., power delivered by a three-phase generator or absorbed by three-phase load is determined by adding the power in each of the three phases. In a balanced circuit this is the same as multiplying the power in any one phase by 3 since the power is the same in all phases.
